Roller- compacted concrete (RCC) is a concrete of no-slump consistency in its unhardened state that is transported, placed, and compacted utilizing earth and rock fill construction equipment. This report includes the use of RCC in structures where measures should be taken to cope with the generation of heat from hydration of the cementitious materials and attendant volume change to minimize cracking. Materials mixture proportioning, properties, design considerations, construction, & quality control are covered. Contents: 1.1--General 1.2--What is RCC? 1.3--History 1.4--Advantages & disadvantages
